This invention relates to a combination socket wrench, and it consistsin connecting a socket ratchet head to the socket handle, and utilizingthe ratchet head as a receptacle for interchangeable sockets. It furtherconsists in the novel means for detachably connecting the ratchet headto the handle, and the interchangeable sockets to the ratchet head.

Referring to the accompanying drawing:

Figure 1 represents the combined tool carrying an interchangeablesocket;

Figure 2 is a detail view of the inner face of the socket handle lookingin the direction of arrow a of Figure 1;

Figure 3 is a detail view of the ratchet head looking in the directionof arrow b, Figure 1;

Figure 5 is a detail broken view partly in section of the assembledratchet head;

Figure 6 is a broken detail view partly in section of the socket handle;

Figure 7 is a broken View partly in section of the assembled tool and aninterchangeable socket connected therewith;

Figure 8 is a detail view of the recessed or socket end of theinterchangeable socket looking in the direction of arrow d, Figure 7Figure 9 is an enlarged broken view of the ratchet teeth and broken viewof the pawl connected therewith, and

Figure 10 represents a similar view of the ratchet teeth and pawl, butshowing the latter reversed.

The combination tool consists of the handle 1 having the hex recess 2,Figures 2, 6, and 7, formed in the face of the head 3, the split springstud 4, and the ratchet head 5.

The ratchet head 5 has the hex stem 6 adapted to register with the hexrecess 2 of relation with the:handle; f The ratchet head? consistsof:two members,

The member 8 isprovided with recesses 12, 13, the former to admit a part of the socketmember 9, and the latter to receive the stem 1% of the member 9. Thegroove 15 of the stem 14:, and the pin 16 maintain the two parts of theratchet head in workable relation with each other.

The inner surface of the socket member 9 is provided with the teeth 17adapted to be engaged by the spring actuated pawl 18 whose stem 19extends through the cap 20 located in the outer surface of the member 8,Figure 3. The cap 20 is forked to receive the pawl retaining pin 21.

22 represents an interchangeable socket. In other words, one of the manydifferent sized sockets adapted to embrace the various sizes of nuts orbolt heads. While the hex recess 23, Figure 8, may vary in size andshape in these interchangeable sockets, they will all have a stem of thesame size and shape as the hex stem 2% to register with the hex recess10 of the ratchet head, and each will be provided with an openingsimilar to the opening 25, Figure 7, for the split stud 11 The handlerod 26 gives the necessary working leverage for the tool. This rod islongitudinally adjustable so that the tool can engage a bolt headwhenever there is room for the tool to rotate.

In operating the tool, the proper interchangeable socket member havingbeen selected and attached thereto, the tool can be rotated right orleft by simply changing the position of the pawl 18, Figures 9 and 10. I

The advantage of the split stud connection between the handle andratchet head, and between the ratchet head and the various intel-changeable socket members, is that the frictional engagement ofthese studs will effectually prevent accidental displacement of theseveral associated members, and they can readily be separated whennecessary by an applied force greater than the frictional I engagementof the :said studs. Another ad- ,vantage of these'spring studs is thatitis not necessary to observe a close fit of the several hexagonalparts,'which may hesquare or of any other angular sha Having thusdescribed my 1nvention, what I claimas new is:-- a g 1.
